88 Claims.

The present invention relates to machines for handling sheet material,and more particularly such sheet material as newspapers and'periodicals.

In copending applications, Serial Nos. 43,928 and 104,628, respectivelyiled on October 7, 1935, and October 8, 1936, of the latter of which thepresent application is a continuation-in-part, there are disclosedmachines for collecting, into bundles or stacks, newspapers as they aredelivered from the press, or returned newspapers, magazines and thelike. The newspapers are first automatically separated out from ahopper, after which they are counted, in `order that the bundles orstacks shall contain predetermined numbers of newspapers to be forwardedto various newsdealers, on order. The values of these,

predetermined numbers, which are different for the diierent newsdealers,are determined by suitably designed plates, which may be address plates,one corresponding to each newsdealer. As disclosed in application,Serial No. 104,628, the same type of plate may be employed for all thevarious newsdealers, but provided with adjustable lugs the adjustment oiwhich corresponds to diiieren't numbers.

The present application contains claims directed to features of noveltymore particularly related to the delivery end of 'the machine, and anobject of theinvention is to provide novel guide-raising,table-rotating-and-lowering, and other mechanism for use moreparticularly at such delivery end of the machine.

A further object of the invention is to provide a new and improvedmachine for collecting the papers in stacks each constituted of groups,with vthe papers of adjacent groupsfacing in opposite directions.`

Other and further objects will be explained hereinafter, and will beparticularly pointed ou in the appended claims.

Fig. 32 is a circuit diagram.

A plurality of newspapers 2 are shown in Fig. 1 in lapped relation, uponinclined continuously traveling conveyor belts 3, mounted over pulleysI4 and III, the former mounted upon a Shaft I. The left-hand ends (asshown in Fig. l) of the inclined conveyor belts 3 may be disposedadjacent to a newspaper press (not shown), a. stack of newspapers (notshown), another conveyor 82, or any other source of supply ofnewspapers. The belts 3 receive the newspapers 2 from the source ofsupply and feed them under a lower projecting `finger of an inclinedlydisposed shield wall 5, disposed in the path of travel of the papers,just beyond the right-hand ends of the conveyor belts 3, into a hopper339, between the wall and a similarly inclinedly disposed shield Wall'I'he shield wail I Iy is also disposed in the path of travel of thepapers, as will hereinafter appear, and its lower end is provided with asimilar lower projecting finger i6.

Though the machine is shown in connection with newspapers, preferablyfed with one of the folded edges l forward, it will be understood thatother sheet material, such as magazines and other periodicals, may alsobe treated in this machine, or parts thereof; and the terms newspaper,paper, sheet, and the like, will therefore, to avoid circumlocution oflanguage, be often employed in the specification and the claims, in thisn generic sense, except where the context or the state of the artrequires otherwise.

If the hopper 339 is empty, the newspapers 2 are conveyed thereinto bythe conveyor 3 under the shield wall 5, and on to a conveyor that isdisposed at the bottom of the hopper 339, Iconstituted of inclinedlydisposed continuously traveling belts 9. The belts 9 are spaced slightlybelow the said. projecting nger I6, but the space or gap or openingbetween them may be blocked or closed, as hereinafter described. Thenumber of belts 9 is shown in Fig. 3 as four, with spaces between them.The belts 9 travel continuously forward, at a higher speed than thebelts 3, over pulleys 32 and 34 and idler rolls |93. The pulleys 32 aremounted upon a shaft 253, adjacent to the right-hand ends of theinclined conveyor belts 3, at the left-hand end of the hopper 339, asviewed in Fig. 1. The pulleys 34 are disposed a considerable distance tothe right, beyond the confines of -the hopper 339.

As the first newspaper 2 is delivered by the conveyor belts 3 into thehopper 339, it is carried by the belts 9 forward, or toward the right,as viewed in Fig. 1. When the said space or opening between the fingerI6 and the belts 9 is blocked or closed, this rst newspaper 2 willengage the shield wall I I, so that the further progress of this firstnewspaper 2 will be temporarily blocked. The second newspaper 2 issimilarly carried forward, to the right, on top of the first newspaper2, until its further progress is similarly blocked. The third newspaper2 is similarly carried forward, to the right, on top of the secondnewspaper, into similar engagement with the wall Il, and so on.

The conveyor 3 continues thus to feed the papers 2, in superposedrelation, into the hopper 339, until the level of the stack of papersthus accumulated therein is high enough to touch the bottom projectingfinger of the shield 5. as shown more particularly in Fig. 1. As no moresheets can then be fed past the shield 5, the level of papers on thebelt 3 in the hopper 339, and their consequent weight upon the belts 9,will be practically constant.

When the said space between the finger I6 and the belts 9 becomesopened, as will be explained more fully hereinafter, the conveyor belts9 will feed the lowermost newspapers 2 in the hopper 339 forward, underthe shield I| and into the space outside, to the right of the hopper339, as viewed in Fig. l. The next-lowest paper will then be simularlyfed out of the hopper 339, and so on. The shield wall I I may be madeadjustable to regulate the said space between the finger I6 and thebelts 9, thereby to control the number of newspapers 2 passingthereunder at any one time.

It is usually preferred to have only one newspaper at a time pass out ofthe hopper 339, under the finger I6. To effect this result, the saidspace near the belt conveyor 9, under the finger I6, should be adjustedso as to be less than the thickness of two newspapers, so that thesecond newspaper from the bottom shall be caught by the sloping, innerwall of the inclined nger I6, as illustrated more particularly in Fig.l. As a slight space or opening separating the lower end of the sheetabove the conveyor 9 will suice to pass the sheets singly, the lower endof the shield Wall Il of the hopper 339 may be disposed very close tothe conveyor 9.

ter the papers have thus been caused to travel out of the hopper 339,they are fed further forward toward a table 9 I, on which they becomeaccumulated in the form of a stack 89. During the feeding of the papersout of the hopper 339, and before they reach the table 9| they arecounted. As each newspaper 2 advances from left to right,

as viewed in Fig. 1, out of the hopper 339, itsy forward edge engages,and passes under, a counting finger I3, disposed above the right-handportions of the belts 9. The nger I3 is integrally xed to a horizontallydisposed shaft |54, about which it is pivotally actuated toward theright by the traveling newspapers, becoming thus raised, in oppositionto the force exerted by a two-way leaf spring |94, above a supportingplate |21 upon which the finger I3 normally rests.

'I'he two-way leaf spring |94 ,carries a contact member |64 that, asillustrated more particularly in Figs. 1 and 32, is normally separatedfrom a cooperating contact member |66, carried by a two-way leaf spring|96. 'Ihe leaf spring |96 is normally biased, so as normally to contactwith a limiting stop 6. In response to each pivotal raising of thefinger I3 bythe successive papers 2, as they travel-out of the hopper339, acam |56, that is xed to the pivotal shaft |54, effects engagementof the contact member |64 with the contact members |66, raising the leafspring |96 out of contact with the limiting stop 6. The spring |94continuously engages the cam |56 to force the finger I3 back intocontact with its supporting plate |21 after each paper has traveled onbeyond it, toward the table 9|.

Each raising and lowering of the counting finger I3 will result inregistering a count, as will be hereinafter explained, to indicate thatanother newspaper 2 has been conveyed by the conveyor belts 9 from outof the hopper 339, and stacked on the table 9|.

The contact member |64 is connected, through the leaf spring |94, to aconductor 200, and the contact member |66, through the leaf spring |96,to a conductor 204. The contact member |66 is connected, as illustratedin Figs. 1 and 32, by way of the leaf spring |96 and the conductor 204,to one side of a counter-controlling electromagnetic coil 202. The coil202 is mounted upon a magnet core 325 provided with an armature 329,that is intermediately pivoted at 2 I0. The contact member |64 isdiagrammatically shown, in Fig. 1, as

similarly connected, by Way of the leaf spring 'medium of a conductor26, and grounds 6|4 and 68, through a rectifier-and-lter 319, which isdiagrammatically represented in Fig. 1 by a battery.

At each closing of the contact members |64 and |66, in response to theactuation of the counting nger I3, the circuit of thecounter-controlling electromagnetic coil 202 becomes closed, by way ofthe conductors 200 and 204 to control the actuation of a counter 323.The counter 323 is shown as a ratchet Wheel, provided with slightlyoffset ratchet teeth 2| 6. This ratchet wheel 323 is fixed to a countershaft 2| that extends into the frame of a selector housing |93. Theshaft 2|| is thus driven from the counter 323.

Continuous rotative movement of the counter Wheel 323 is prevented by aspring-controlled ratchet double pawl 321 that is integral with thearmature 329, so as to be pivoted therewith, at 2|0. 'I'he pawl 321 isprovided at its ends, on opposite sides of its pivot 2I0, with twooppositely acting pawl teeth for engaging the ratchet teeth 2|6 of theratchet counter wheel 323. One of the teeth of the ratchet pawl 321 isheld normally in engagement with a ratchet tooth 2|6 of the counterwheel 2|8 by a spring, diagrammatically shown in Fig. 32 at 222. Uponthe closing of the circuit of the electromagnetic coil 202 `by thecontact members |64 and |66, in response to the actuation of thecounting finger I3, the armature 329 will be actuated by the energizedcoil 202 about its pivot 2I0, clockwise, as viewed in Figs. 1 and 32, inopposition to the action of the spring 222. The pawl 321 will be rockedabout the pivot 2|0 with the armature 329 upon which it is mounted,effecting the separation of the said pawl tooth of the ratchet pawl 321from the said ratchet tooth 2|6. 'Ihe other tooth of the pawl 321 is, atthe same time, actuated into engagement with another tooth 2|6, at theopposite side of the ratchet wheel 323. The next moment, the nger I3, asthe paper 2 thereunder passes beyond it, will 'be actuated by the spring|94 to effect the actuation, in the opposite direction, of the cam |56,and the consequent separation of the contact members |64 and |66. Thiswill result in the opening of the circuit'of the coil 202.

The spring 222 will thereupon rock the pawl 321 inthe oppositedirection, counter-clockwise, as viewed in Figs. 1 and 32, to cause thesaid other pawl tooth,y of the pawl 321v to release its tooth 2|6, andthe first-named tooth of the pawl 321 to engage'another tooth 2|6 of theratchet wheel 323. 'I'he double pawl 321 is thus actuated with thearmature 329 by the magnet coil 202 and the spring 222 like an ordinaryescapement pawl, with its pawl teeth engaging oppositely disposed teeth2|6 of the ratchet wheel 2I8 alternately. The counter wheel 323 is,therefore, rotated step-bystep by the pawl 321, through successiveangular distances corresponding to one tooth 2|6 for each paper 2.Successive movements of the counting wheel 323, tooth by tooth, onetooth at a time,

may become thus registered on a dial (not shown), to register a totalcount corresponding to the total number of papers 2 fed by the conveyor9 out of the hopper 339. The counting wheel may make a 25th of arevolution for each paper counted.

The shaft 2|| rotates a contact arm 2|3 (Figs. 19, 20, 28 and 32) over,so as successively to engage, 25 contact members 2|5 that are disposedvin a circular row, and that are numbered 0 to 24 in Fig. 28. A contactarm 2 1 is similarly adapted successively to engage 13 contact members2|9 that are disposed in a second circular row, and that are marked 0,25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275 and 300 in Fig. 28.The connection between the arm 2|3 and the shaft 2II is frictional,through the medium of a disc clutch.

235 that is pressed, by a spring 406, against an intermittent gearmember 259 (Fig. 20) fixed to the contact arm 2|3. All the contactmembers 2|5 will be successively engaged inthe course of one revolutionof the arm 2 I3. The gear member 259 is so arranged with reference to atrain of gears 400, 403 and 40| that, as the arm 2 I3 passes from the 24contact member 2|5 to the 0 contact member. 2|5, it will actuate thecontact arm 2|1 through the intermittent gearing, 164th of a revolution,from one contact member 2|9 to the next contact member 2|9. The gears400 and 403 are integrally connected together, the former meshing withthe g'ear member 259 and the latter with the gear 40| The gear 40| ismounted upon a shaft 401 that drives the contact arm 2|1 frictlonally,in the same manner that the shaft 2|| drives frictionally the contactarm 2I3, through the same kind of clutch 235, pressed by a spring 405against an intermittent 'gear member 229 to Whichthe contact arm 2|1 isfixed.

The circuits of the contact members 2|5 and 2I9, respectively, as willhereinafter appear, are

. further controlled by previously closed pairs of contact members 206,201 under the control of the lugs 20| on the address plates 205.

'As shown arbitrarily, there are twenty-five pairs of contact members206numbered 0 to 24 in Fig. 23, and thirteen pairs of contact members201, marked 0, 25, 50, 75, 100, 125, 150, 175, 200, 225,250, 275 and 300in the same Fig. 28. The

maximum cou'nt of the unit row 206, therefore, is.

24, the 25th and its multiples being counted on on the group row 201.

\\course, be applied to each row, but in the case of newspapers, 25 isconvenient as they are turned irigroups of 25 or multiples of 25.

Two rows of contact members 206 and 201' are shown because, for thequantity to be covered, accuracy and convenience could not be obtainedby placing 300 contact members in one row. The contact arm 2I3constltutesa units-counter control, cooperating with the contact members206, and the contact arm 2|1 constitutes a multiplecounter control,counting by multiples of 25, and cooperating with the contact members201. The contact arm 2 I3 may, therefore, be referred to as the unitscounter and the contact arm 2 I1 as the multiple counter.

Each of the contact members 2|5 is wired to one of the sets of contactmembers 206, and each of the contact members 2|9 is wired to one of thesets of contact members 201, as shown in Figs. 28 and 32. The first orcontact member 2|5, for example, is connected by a conductor 4|3 withthe first or 0 pair of, contact members 206; the second or 1 contactmember 2|5, by a conductor 4 5, with the second or 1 pair of contactmembers 206; the third or 2 contact member 2 I5, by a conductor 4|1 withthe third or 2 pair of contact members 206; the thirteenth or 12 contactmember 2|5 by a conductor 36 with the thirteenth or 12 pair of contactmembers 206; and so on; the .last or 24 contact member 2|5 beingconnected by a conductor 4 I 9 with the last or 24 pair of contactmembers 206. The first or 0 contact member 2|1 is similarly connected bya conductor 32| with the first or 0 pair of contact members 201; thesecond or 25 contact member 211, by a conductor 523, with the second or25 pair of contact members 201; the third or 50 contact member 2 I1, .bya conductor 425, with the third or 5G pair of contact members 201; andso on; the last or 300 contact member 2I9 being connected by a conductor421 with the last or 300 pair of contact members 201.

After leaving the counting finger 13, the papers 2 are fed into the bitebetween vertically disposed continuously traveling lift belts I1 and 2|of a conveyor that feeds the newspapers 2, as they are received from thehopper 339, vertically upward. The conveyor belts l1 pass over a lowerpulley or roll 51, fixed upon a shaft 255, a discharge pulley or roll21, and smaller pulleys or rolls 3|, d5 and 41. The conveyor belts 2|pass over the pulley 21, an intermediately disposed pulley 59, i'lxedupon a shaft 25d, and an idler pulley 23. To maintain tension in thebelts 2|, the idler pulley 23 is free to move in a vertically disposedarc at the end of arms pivoted to the frame of the machine at |03.

If the inclinedly disposed conveyor belts 9 travel at a slower speedthan that of the lift belts i1 and 2 I, the papers 2 will separate outmore rapidly in the hopper 339, and congestion and buckling of thepapers 2, that might be caused by slippage between the belts and thepapers 2, will be avoided. The desired relative speeds may be producedin any desired manner, as explained in the said applications.

In order to maintain the point of delivery of the papers 2 above thetopmost paper of the stack 89, the delivery end of the conveyor,including the upper portions of the belts I1 and 2|, and the rolls 21and 3|, is disposed above the belts 9 and the table 9|. The dischargepulleys or rolls 21 and 3| are carried by arm members 31 that are Anynumber may, ofV

is pivoted at 35 to an arm 4|.

freely movable vertically. In this vertical movement, they are guided bywheels I 5, that are carried by the arm members 31, so as to roll on avertically disposed track of a supporting column 42|.

Upon reaching the bite between the conveyor belts |1 and 2|, the papersare turned upward, around the'large pulley 51, and toward and over thepulley 21. Each paper 2 is then fed from above the table 9|, at the leftthereof, as viewed in Fig. 1, at a downward incline, on to the top ofthe stack 89 accumulated on the table 9|. During this downwardlyinclined feeding, the papers travel over a downwardly inclined guide armor arms 39, and under downwardly inclined guide arms or members 55,toward and against stops, constituted of integrally bent portions 58 ofthe guide members 55. The bentvv portions 58 project downward, so as tobe engaged 4by the forward edges 1 of the newspapers, to limit thefurther travel of the papers. The newspapers thus become successivelydeposited on the top of the stack 89 on the table 9|, each on top of thepreviously deposited paper 2, in engagement with the stops 58. The stack89 rises higher and higher as the newspapers are successively conveyedthereto, until the desired number of newspapers,

as determined by the count of the counting iinger I3, has been collectedin the stack 89. The guide members 55 constitute part of the elevatorassembly that moves up with the discharge pulleys or rolls 21 and 3| asthe heightof the stack 89' increases.

The guide members 55 are respectively disposed at opposite sides of thecenter of the stack 89 of the papers, and predetermine the positionoccupied by the stack 89 on the table 9|. To equalize the pressureexerted by them on the uppermost sheet of the stack 89, these two guidemembers 55 may be separated by a yoke 59 that The guide members 55 arethus always maintained in proper position for guiding the papers to thetop of the stack 89.

Through'the medium of the yoke 49 and the arm 4|, the freely movablerolls 21iand 3| and the arm members 31 by which they are carried, theupper portion of the conveyor 2|, and related parts, are automaticallyraised vertically, in accordance with the height of the stack 89. Thisis effected by the impact of the papers, passing under the guides 55, inopposition to the force of gravity. The weight of the parts and a spring119 normally maintain the guide arms 55 yieldingly in engagement withthe top of the stack 89 and pressing yieldingly downward thereon. Toreduce the upward force which the papers must exert in order to lift theguide members 55 higher and higher as they travel thereunder, acounterweight |44 is connected to the members 31 by cords i122, runningover pulleys |3| and |29.

The idler pulley 23 and related parts move up and down with the deliveryend of the conveyor I1, 2|. The lowermost positions of the pulleys 21and 3| and the arms |0| with the idler pulley 23 are indicated in Fig. 1by dotted lines.

At such times as the said space under the iinger I6 and above the belts9 is blocked, so as to stop the further feed of the newspapers 2 o utofthe hopper 339, it is desirable' that thecontinuously traveling belts 9do not engage theA lowermost newspaper 2 in the hopper 339. Provisionis,

of the other parts of the machine. The mechaanism for bringing thisabout will now be described.

A tabl I2 is constituted of a plurality of bar supports respectivelydisposed between the belts` hopper 339, through the said space under thefinger l5. Upon the completion of a cycle of operations,immediatelyafter every feeding of the desired predetermined number ofpapers 2 out of the hopper 339, the table I2 is raised pivotally as aunit about the rod |25, from its normally ineffective position, upbetween the belts 9, intoits effective position. 'I'his may be broughtabout in any desiredmanner, as by a half-revoluton of a cam |05, mountedupon a rod or shaft |10,as more particularly illustratedsin Figs. 1, 2,3, 8 and 32. The shaft |10 is journaled in the front and rear frameplates or walls |65 and |61 of the machine. It is this raising of thetable I2 that results in blocking the said gap or space under the ngerl5, thus stopping the further feed of the papers out of the hopper 339,below the shield I. also, however, in lifting the newspapers 2 up' oithe belts 9, so that the belts 9 could not further convey the newspapersout of the hopper 339 even if the said space were not blocked. Upon thelowering of the table I2 from its eective position, 4above the belts 9,to its ineffective position, below these belts, the feeding of thepapers 2 out of the hopper 339 by the belts 9 recommences, and themachine goes through another cycle of operations.

The raising of the table |2, upon the complestion of each cycle ofoperations, is automatically edected by the cam- |05, in synchronismwith the operation of the rest of the machine. It is similarlyautomatically'lowered at the commencement of a new cycle of operation,and also, when first starting the machine into operation, upon theclosing of a line switch 293 (Fig. 32) through the medium of circuit-connections described hereinafter.

The feeding and stacking of the papers 2 may be stopped manually at anytime by opening the switch 293. By opening a switch 533 in the circuitof a lower table-raising electromagnetic coil 3I9, the machine will bepermitted to contnue feeding the papers out of the hopper 3391 until thehopper is completely emptied.

The pivotally mounted rod |10, upon which the cam |05 is mounted, isactuated through semirevolutions by means of the lower table-raisingelectromagnetic coil 3|6 and an upper table-lowering electromagneticcoil 3|8, shown more particularly in Fig. '8, and diagrammatically inFig. 32. The circuits of these electromagnetic coils 3I6 and 3|8, aswell as of other electromagnetic coils illustrated herein, are openedand closed, as described hereinafter, and also atconsiderable length inthe said applications, by the counterand-selector mechanism, under thecontrol of the counting nger I3. One semi-revolution of the shaft |10,in response to energization of the coil 3|6, at the end of a cycle ofoperations, re-

sults in the cam |05 raising the table I2 to stop the feed. The nextsemi-revolution of the shaft It results spring |10, in'response to theenergization of the coil 3I0, at the commencement of a new cycle ofoperations. results in the lowering of the cam |95, and the consequentlowering of the table I2 by gravity, whereupon the feeding of the papers2 out of the hopper 339 by the belts recommences.

A drum I13isxedtothe shaft |10,asshown.

more particularly in Fig. 8, by means of a Woodrufli key |15. -Ahalf-revolution of the drum |13l will, therefore, result in raising thetable |2 to its effective position, so as to close the gap under thefinger I9, as before described, to stop the feed of the papers out ofthe hopper 339, and a further half-revolution of the vdrum |13 willresult in relowering the table |2 toits ineective position. Thesehalf-revolutions are effected by clutching the drum |13 to a cylindricalbarrel 345 to which the; cam |05 isv integrally secured. and that isnormally mounted loosely on the 'shaft |10, so as to be free to turnthereon. The barrel 345 serves also as a housing for the drum |13. Thedrum |13 is constantly rotated, at constant speed, from a pulley (Figs.2. 3 and 8) that is mounted at one end of the shaft |10. The clutchingof the barrel 345 to the constantly rotating drum |13 is effected bylmeans of a coiled spring |11 that is wound around the outside ofthedrum |13. One end |92 of the spring |11 is held ina hole |19 in the cam|05, and theother end I9| is held in a hole'lll of a collar or disc |83that normally is loosely mounted on the shaft |10, so as to turn freelythereon.

When the spring |11 is free to do so, it will.

through its own resiliency, engage and wind itself tightly about theconstantly rotating drum |13, so as to become tensioned thereagainst,.byfriction. The spring |11 will then be caused to rotate with the drum|13, carrying with it the collar |93 and the barrel 345, and therebyeffecting they rotation of the cam |05, to which the barrel 345 isintegrally secured. The tensioned spring |11 thus effects the clutchingof the shaft |10 to the cam |05 so as togbecome rotated from the pulley55. The cam |05 becomes unclutched from the constantly rotating drum|13when the spring |11 is caused to unwind itself therefrom. Themechanism for effecting -this winding and unwinding of the |11 and .theconsequent intermittent clutching and unclutching of the cam |05 willnow be described. y

A. lower armature 304 cooperates with the lower table-raisingelectromagnetic coil 3|5, and an upper armature 302 cooperates with theup-v per table-lowering electromagnetic vcoil 3|3, as illustrated inFig. 8. Ihe armatures 302 and 304 are disposed opposite to each other,at the upper and lower ends of a yoke 306 that is pivoted to move to theright and to the left, as viewed in Fig. 8, about pivots 308 and 3|0,that enter suitable journals in the central common core 3|2 of themagnetic coils 3|5 and 3|8. ,f

At times when the circuit of the lower ele'ctromagnetic coil 3|8 isclosed, the circuit of the upper electrom-agnetic coil 3|8 is open, andvice versa. The energization of the upper electromagnetic coil 3|8 willresult in pivotal actuation of the upper armature 302 to the right, andthe'lower armature 304 to the left, as viewed in Fig. 8, about thepivots 308 and 3I0; and the energization of the lower electromagneticcoil 3I5 will result in similar actuation of the armatures 302, 304 inthe opposite directions.

Near 'the circumference, a lug 300 extends though both faces of the disc|83. The righthand end of the lug 333, as viewed in Fig. 8, is adaptedto be engaged either by the upper armature 302 or the lower armature304, depending upon which 'of them has been actuated toward the left, asviewed in Fig. 8. The lug 300 becomes released from its engagement withthe corresponding armature 302 or 304, however, when that particularamature becomes pulled over toward the right by its actuating coil 3|8or 3|6, respectively. The lug 300 will thereupon become rotated, by thespring |11, into engagement with the other amature 304 or 302,

which has become actuated, about the pivots 308 and 3|0, toward the leftat the same time that the amature 302 or 304, respectively, was actuatedtoward the right. The upper armature 302 will thus engage the lug 300when the lower amature 304 has been pulled to the electromagnetic coil3|6, and the lower armature 304 will engage the lug 300 when the upperarmature 302 has been pulled to the electromagnetic coil 8I8.-

Immediately upon the disengagement of the lug 300 from the lowerarmature 304, in response to the actuation of the latter toward theright, as viewed in Fig. 8, the spring `|11 will wind itself tightlyabout the constantly rotating drum |13, effecting the before-describedclutching of the cam |05 to the shaft |10. 'I'he cam |05 will thenrotate with the shaft |10 for a half-revolution. More than ahalf-revolution of the cam |05 is preventedby the lug 300 on the collar|83, during its rotation in its circular path about the axis ofrotation-of the drum |13, coming into engagement with the upper amature302. 'I'he rotation of the collar |83 will thus become interrupted, andthe end I3| of the spring |11 will be held back from further rotation.This will effect a partial unwinding of the springs |11 from itsfrictional engagement with the drum |13, so as to render it loose againupon the drum |13. 4The drum |13 will continue to rotate with the shaft|10, but the barrel 345 and the cam |05 secured thereto will have becomeunclutched therefrom. The cam |05 willv thus become stopped in its upperposition, with the table I2 raised to its upper eective position, inwhich the papers 2 can not be fed out of the hopper 339.

When the lug 300 becomes disengaged from the upper armature 302,similarly, the cam |05 will become rotated with the shaft |10 throughanother half-revolution, until the lug 300 of the collar |83 reengagesthe lower armature 304. As the armatures 302 and 304 are positioneddegrees away from each other in the path of rotation of the lug 300 ofthe collar |83, the cam |05 will, this time, be stopped in its lowerposition, to permit lowering of the table I2 by gravity to itsineffective position.

To control the degree of unwinding of the spring |11, so that the cam|05 shall stop, each time, at the same point of its lower or upperposition, respectively, the portion of the lug 300 on the left-hand sideof the disc |83, as viewed in Fig. 8, is caused to engage always thesame end wall of a slot |85, that is cut in a ange |58 of thecylindrical barrel 345.

'I'he armatures v302 and 304 thus operate in alternation, to interruptthe rotation of the cam |05 at the endof each half-revolution thereof.In response to the. successive closings of the circuits of the upper andthe lower electromagnetic coils 3|8 and 3|8, therefore, the camI05'becomes rotated through successive half-revolutions to eectintermittent actuation of the table I2, up

Y arcanes land down, into its two effective and ineffective A positions.

through-the closing of a contact member 514 (Figs, 14 to 16 and 32), toclose the circuit of the upper electromagnetic ,table-lowering coll 3|8.The half-revolution of the cam |05 that effects the raising of the tableI2 is broughtabout through the closing of the circuit of the lowerelectromagnetic table-raising coil 3I6.

Similar spring-controlled clutches are under the control of othersimilar electromagnetic coils. A shaft 48 is provided with a.continuously rotating pulley |38 (Figs. 2 and 3); shafts 11 and 84 areprovided with continuously rotating sprocket gear wheels |32 and 251,respectively (Figs. 2 to 5); and a shaft 32| is provided with acontinuously rotating sprocket gear wheel 335 (Figs. 2, 3 and 30). Theseshafts, journaled in one or both side frames |65 and |81, are drivenintermittently from their respective continuously rotating pulleys'andgears similarly to the man- `ner in which the cam |05 on the shaft |10is intermittently rotated by the pulley 58. The shafts 48 and 11, forexample, are each provided with two coils 3|6 and 3|8, the same as theshaft |10, to eect their intermittent actuation. through halfrevolutions, in the same way as before described, through the medium ofintermittently actuated drums |13.

The shafts 32| and 84, however, are actuated intermittently throughcomplete revolutions, instead of through only half-revolutions. The twosets of electromagnetic coils 3|Ii and 3|8 are, therefore, replaced, inthe case of the shafts 32| and 84, by only a single coil 332 providedwith but a single armature 334 (Figs. 9 to 11). The mechanism fordriving the intermittently rotating shaft 32| will now be described; theshaft 48 is actuated in similar fashion.

'I'he constantly rotating sprocket wheel 335 is mounted upon a drum |13that ls loosely mounted upon the shaft 32|. A spring 341, mounted aboutthe drum |13, corresponds to the spring |11. As illustrated in Figs, 10and 11, the armature 334 normally engages a lug 33 8 on the periphery ofa floating ring 340, which corresponds to the lug 300 of the collar ordisc |83 of Fig. 8. A slot 342, corresponding to the slot |85, isprovided in one end of a cylindrical case 344, corresponding to thebarrel 345. The case 344 is fixed to th shaft 32|, as by means of a nut35.

Upon the closing of the circuit of the coil 332', the armature 334 willbecome attracted to the core 331 of the coil 332, in opposition to theaction of a flat spring 339, thereby becoming released from itsengagement with the lug 336. The spring 341 will thereupon wind itselfabout the drum |13 to clutch the shaft 32| thereto. Immediatelythereafter, the spring 339 will return the armature 334 to its normalposition into the path of travel of the rotating lug 336 of the floatingring 340. 'I'he armature 334 will thereupon become reengaged by the lug336, therefore, to unclutch the shaft 32| after a complete revolutionthereof. In other respects, the operation is substantially the same asdescribed above in con-- nectlon with the electromagnetic coils 3|8 and3|8 and their armatures 302 and 304.

As more fully explained hereinafter, the shaft 48 controls the raisingand lowering of the guide members 55, the shaft 84 effectshalf-revolutions of the table 8| between the feeding of successivegroups of papers to the stack 89, the shaft 11 eects the lowering. ofthe table 9|, resulting in removal of the completed stack 89 therefrom,and the shaft 32| controls the positioning of successive address plates205 for Acontrolling the number of papers in the successive stacks 89.The address plates 205 are initially stacked in a vertically-disposedcontainer, magazine'l or receptacle 216, each address platecorresponding to a diiferent newsdealer' to whom the newspapers stackedon the tble 9| areto be shipped. Each plate 205 is provided at one ofits ends with a cutout 500; and the plates are so positioned in thereceptacle 218 that a vertically disposed slide in'the magazine 216 isreceived in the cutouts 500. This insures that no plateshall be placedin the magazine in Athe reversed position. A slide 232 is positioned inhorizontally disposed guide grooves or ways 309 under the container 216,with the lowermost plate 205 in the container 218 normally restingthereon. The slide 232 is, at the proper time, moved to the right, asviewed in Fig. 1, froml beneath the container 216, so as to permit thelowermost plate 205 in the container to drop into a position from whichthe slide 232 may actuate it toward the left, as described in the saidapplications. The slide 232 will thus move the lowermost plate 205 fromunder themagazine 216 to a denite position underneath a plate 3|3. Theplate 205 previously under the plate 3|3 is, at the same time, movedinto a container 215, over a spring-pressed nger 3|1.v The plates 205are later removed from the container 215 for new use.

When the plate 205 is positioned under the plate 3|3, the manuallyadjusted lugs 20| will respectively become positioned under vpairs ofcontact members 206 and 201 predetermined by the adjustment of -the lugs20| on the address` plate. The plate 205 will remain in this positionduring the counting off of the Papers in the particular stack 89corresponding to this plate 205. Above the plate 3|3, a member 429carries wiring 3|@ through a cover plate 3|5.

The slide 232 is provided with an anti-friction roll 305 that may beengaged between the tines of a forked arm 303. The arm 303 is rockedabout the axis of a pivotal shaft 30| by means of linkseach revolutionof the shaft 32|, it will actuate a crank 328 to rock, through the links30 and 244, the shaft 30| and the forked arm 303. During this rocking ofthe arm 303, it will positively move the slide 232 away from under thecontainer 216 i'lrst, to the right, as viewed in Fig. 1, and then to theleft. As explained in the said applications, the forked arm 303 may bespring-loaded, to prevent possible destruction of the plates 205 orparts of the machine, in the event that there should be an obstructionto the smooth passage of the plates during the actuation of the slide-232; and an adjustable stop or stops may also be employed to limit thereturn movement ofthe slide 232.

As before stated, it is desired to count the sheets in thestack 89 up toa predetermined number, which number is dierent for each individualnewsdealer. The predetermination of the count is effected'by means ofsuitable manually adjustable lugs 20| on the address plates 205. Thepositions to which the lugs 20| are adjusted on the address plates 205determine the number of papers 2 that shall be accumulated in aparticular stack .89 on the table 9|;for'a particular dealer.

7 There are two lugs 20! on each address plate 205 ,(Figs. 22 and 23),manually adjustablev to any of a plurality of positions along respectivescales sus andI m at the sides of the address plate zu.

The divisions of the scale 4|| correspond to units of 25, and thedivisions ofthe scale 409 correspondv to individual counts. It a greatercount is needed, as will be obvious, it is possible to increase whichthe lugs 20| have been normally adjusted on the address plate.

The positions of the lugs 20| on the address plate 205 determine,therefore, which of, the contact members 2|5 and 2|9, when engaged bythe vrespective arms 2|3 and 2 I1, shall eiect a closing oi. the circuitof the lower table-raising electromagnetic coil 3l6, which stops thefeed of lthe papers out of the hopper 339. -The lugs 20| are maintainedin adjusted position on the plates 205 by means of projections 209 onthe bottoms of the lugs 20| extending into openings |95 in Athe plates205.

'I'he electric system is normally ineffective to energize thetable-raising coil 3|6, even though the selected pairs of contactmembers 206 and 201 are thus continuously connected into circuit, inseries with a direct-current source of energy, such as arectiier-and-lter 319, and notwithstanding the engagement of the contactarms 2|3 and 2|1 with selected contact members 2|5 and 2|9. The circuitsfor effecting the desired operations remain open until suitably manuallyadjusted lugs 20|V eect the closing of desired pairs of contact members206 and 201; and then only after operating the machine through a cycleor a group of cycles of operation. The necessary circuits will berendered eiective, in sequence, at the endvof predetermined rotativemovement of the counting wheel- 323, asdetermined'by the counting finger|3, and as controlled by suitable contact members 2 5 and 2 9 whenengaged by the respective contact arms 2|3 and 2|1.

One of the circuits of the coil `3|6, as may be traced in Figs. 28 and32, extends from the rectiiler-and-filter 319 to the ground 6|4'; andfrom a ground 66, through the coil 3|6, the switch 533, and the lowercontact members 201 marked 0, 25, 50, to the pair of contact members 201that are closed by one of the lugs 20|; thence, by way of one of theconductors, some of which are indicated at 42|, 423, 425 and 421, to thecorresponding contact member 2|9. When this contact member 2|9 isengaged by the contact arm 2|1, the circuit continues, b'y way of aconductor 433, to the contact arm 2|3 and the contact member 2|5 thathap'pens to be in engagement therewith; thence, by way of one of theconductors, some of which are indicated at 4|3, 4|5, 4|1, 38 and 4|9, tothat pair of contact members 206 that are closed by the other lug 20|;and

thence, by way of the conductor '26, back to the will effect theenergization of the coil 3|8, thus rendering the circuit effective toactuate the cam |05, as lefore described, to raise the table I2, thus'to s op the feed of the papers 2 by the conveyor 9 out of the hopper339, below the shield i I.

The arms 2|3 and 2|1 can not, by themselvesI effect this result; theycan do this at a predetermined point of their rotation, when theyrespectively engage the proper contact members 2|5 and 2|9, only incooperation with those pairs of contact members 206 and 201, connectedinto circuit therewith, that have previously been closed by the lugs20|. y

'I'he selector contact arms 2|3 and 2|1 and related parts are then resetto the initial positions as a new plate 205 is moved into place. Theshaft 32|, as illustrated more particularly in Figs. 2 and 30, drives,through the medium of a chain 338, the shaft 223 of the selector thatshifts the address plates 205. Pinned or otherwise xed to the shaft 223are gears 221, cut away at 4|5, as shown more particularly in Figs. 19and 20. Two similar but smaller gears 229, on the said shafts 2|| and401, are also cut away. If similar but smaller gears 229, on the saidshafts 2li and 401, are also cut away, the arms 2|3 and 2|1 do notoccupyr their initial positions, the rotation of the gears 221 willbring them into mesh with the gears 229, and rotate them, againstthefriction of the clutches 235, until the cut-away sections are broughtinto the position shown in Figs. 19 and 20, when the gears 221 and 229will no longer mesh, and the arms 2|3 and 211 will then have beenbrought to the starting positions. The

shaft 223 and the gears 221 will continue turning until returned to thepositions shown in Figs. 19 and 20. In this position, the gears 229cannot mesh with the gears 221 when the counting begins. 'Ihis alsovreturns the intermittent gears 259 to its initial position, so that itshall not turn the arm 2 1 until the 25th paper has been counted off.The parts are thus returned to their initial positions by a singlerotation of the shaft 223. At the completion of the count, as describedin the said applications, a wrapper or label, with or any other desirednumber, of papers shall have the folded edges 1 reversed; that is, forexample, so that the lowermost twenty-five papers in the stack 89 shallhavevtheir end and side folded edges facing north and east',respectively, the next twenty-five papers =shall havethose edges facingsouth and west, respectiveiy, the next twenty-five north and east again,etc. Alternating the papers in this manner is desirable for somepurposes, such as to facilitate their being counted by the personsreceiving them, and also to make a more stable stack, with the upperpapers thereof more or less level.

This resultmay readily .be effected by turning the table 9| through 180degrees upon the completion of the feeding and stacking of every groupof twenty-fiveor any other desired number of papers 2. Any desirednumber of groups of ten,

r twenty-five, fty, etc., papers may thus be stacked on the table 9|,with semi-rotations of the table 9| between the stacking of thesuccessive groups.

It is during these semi-rotations of the table 9| that the table I2 israised to prevent further feeding of the papers 2 out of the hopper 339by the conveyor 9. Before each semi-rotation of the table 9|, the guidemembers 55 are raised, from their normal effective positions, up toineffective positions, above the stack of papers 39; and after eachsemi-rotation of the table 9|, the guide members 5 5 are relowered totheir normal eiective positions.

The table 9| is turned by rotating a vertically disposed shaft 95 uponwhich it is mounted. Half-rotations of the shaft 95 are effected, intimed relation to the operations above described, by means of ahorizontally disposed rack bar 43|, that meshes with a gear 432 securedto the shaft 95. The rack bar 43| is slidably actuated horizontally, rstto the right, and then to the left, as viewed in Figs. 1 and 5, inguides 509. The

'slidable actuation of the rack bar 43| is eected by means of a crank429 that is connected to the rack bar 43| by a link 430. y'1"he crank429 is secured to'a shaft 428, provided with a gear 4 that is driven bya. gear 8S on the shaft 84 (Figs. 3 to 5 and 25). The connections are sodesigned that, corresponding to a half-revolution of the shaft 428, theshaft 95 shall be turned through a half-revolution; and when the shaft428 is turned a further half-revolution, to its original position, theshaft 95 shall likewise be turned a further half-revolution to itsoriginal position. These half-revolutions are eiected at the end of thefeedingof the papers 2 in groups of twenty-five, or any other desirednumber. The driving conlnectlons will be described hereinafter.

To effect the raising and lowering of the guide members 55, they arerendered pivotally movable upward, in substantially vertical planes,about a pivot 45|, in opposition to the action of the spring 4|9. vThismay be effected in any desired manner, as by moving a verticallydisposed link 443 toward the right, as viewed in Fig. 1, into engagementwith a pin 44| mounted upon an arm 435 that is fixed to the arm 4|. Thelink 443 is maintained always parallel to itself by a link 449 and abell-crank lever 444 to both of which it is pivoted. The bell-cranklever 444 is actuated by means of a link 445 from a crank pin 441 on theshaft 48.

In the course of one complete rvolution of the shaft 48, after the tablel2 has been'vraised to stop the feed out of the hopper 339, the link 443is actuated upward and to the right, as viewed in Fig. 1. This resultsin swinging the guide members 55 upward, about the pivot 45|, away fromthe stack 8,9, into their ineffective positions, illustratedin'Fig. 6.The pin 44| is covered with friction material, such as rubber orleather, the frictional binding of which against the link 443 preventsthe elevator assembly from dropping while the guide members 55 areraised above the topmost paper in the stack 89. i

An extension 53 prevents the guide members 55 from dropping below acertain level when the connecting rod 443 has been dropped to one side,and prevents frictional contact between the friction lugf44| and theconnecting; rod 443 at such times as the guide assembly should be freeto move vertically.

, During the time that the guide members 55 are raised, the table 9| andthe stack 89 thereon are turned a half-revolution (in Fig. 6, theposition of the table9| is illustrated at the moment when aquarter-revolution has been effected), after which the shaft 48 isrotated through another half-revolution, to return the link 443 from theposition oi Fig. 6 to the position of Fig. 1, thus restoring the guidemembers 55 to their normal effective positions.

papers out of the hopper 338 by the conveyor 9. Upon the feed becomingresumed, the papers will, this time, however, become stacked on thestack 89 in reversed` position,- with the said forward folded edges 1 ofthe papers 2 disposed on the stack 89 oppositely to the forward edges 1of the prior-fed papers.

At the end of the counting of the predetermined number of papers desiredto be attacked for any particular dealer, and their accumulation in thestack 38, the stack 88 is removed from the table 8i. To this end, thetable 8Hs shown constituted of a frame comprising parallel horizontallydisposed slats 52, alternating in position with the positions ofvsimilarly disposed elongated rolls 523 mounted on shafts 48. The'rolls523 are con- ",tinuously rotated from a continuously driven shaft 33 bybelts 428 engaging over pulleys 425 The cam 99 is actuated throughsuccessive halirevolutions in response to half-revolutions of the shaft11. A cam follower 421 disposed at the lower end of the table shaft 95follows the cam 89 downward in engagement therewith, carrying the table8l with it. A further half-revolution of the shaft 11 results inrestoring the cam 99, and, therefore, the table 9i, to their normalpositions. The face of the gear 832 is wide enough so as vto remain inmesh with the rack d3i f both when the table 8i is in its uppermost andits lowermost positions.

To effect removal of the stack of sheets, the table 8l is lowered belowthe continuously rotating rolls 523, with its slats 52 into the spacesbetween these rolls. The lowering of the table 8i effects the loweringof thestack 89 of papers 2 into contact with the rolls 528. The stack 88becomes thereupon moved by the rolls 523 01T the table 9i and on to atable (not shown) at the sidel of the machine, either in front of orbehind the papers, as`viewed in Fig. 1.

One of the bars 186 of the table i2, that becomes periodically raised tostop the feed of the papers out of the hopper 339, is provided with aprojection 358, that is adapted to engage a plunger 352, to raise it, asillustrated more particularly in Figs. 2, 12 to 16, 18 and 32. Theplunger 352' depends through an opening 35i (Figs. l5 and 16) in thelower wall 355 of a commutator or control box 353 (Fig. 2), and issecured to the underside of two insulating, contact-engaging members 351and 359, that are secured together at different levels. Thecontact-engaging member 351 engages under a contact member 358 and thecontact-engaging member 358 engages under a contact member 362. Thecontact members 358 and 352 are disposed at correspondingly differentlevels, as illustrated in Figs. 12 to 16 and 18. The raising of theplunger 352 bythe projection 358, therefore, will effect the raising ofthe two contact members 356 and 362. When the table IZ ocupies its lowerposition, a contact member 358 is out of contact with the contact member856 The table I2 is then relowered to permit resuming the feed of the-and a contact member 388 eng-ages the contact member 352. Theraising ofthe plunger .352" by the projection .358, therefore, will result in theopening of the contact members 388 and 362, and theclosing of thecontact members 356 and 358. The opening of the contact members 360 and382, as hereinafter explained, eifects the breaking of the circuit ofthe table-raising coil 318, previously closed to effect the raising ofthe table I2. The closing of the contact members 356 and 358, asalsohereinafter explained, effects the closing of the circuit of acommutator-drive motor 384 on the shaft of which are connectedmultiple-switch master-control switch arms 518 and 519 that areinsulated from each other by an insulating collar 320. The electricalconnections are shown diagrammatically in Fig.,32. Suitable speedreducers keep down'the speed of the shaft of the motor 364 to a desiredlow speed. As soon as the table I2 becomes raised, therefore, at the endof each cycle of operation, by the closing of the contact members 356and 358, the motor 364 is operated throughout a complete revolution tocontrol the rotation of the master-control switches 518 and 518. As willhereinafter appear,

only one of the two master switchesf518 and 519 is eective at any onetime, during any particular revolutionrof the motor 3188.

The master switches 518 and 519 are shown in Figs. 16 and 31respectively connected to contact brushes 54 and 56. 'I'hese are omittedfrom the diagrammatic showing of Fig. 32.

The operations of the machine are synchronlzed by the master switches518 and 519, in the course of one complete revolution thereof, by themotor 368. In the course of this complete revolution, the master switch518 is caused to engage successively contact members 568, 510, 512 and516, and the master switch 519, contact members 568, 318, 312, 314, 512and 514. These contact members are set into an insulating disc |68.

When the master switches 518 4and 518 engage the contact member 568(Figs. 15 and 32), the guide members 55 become raised. When the masterswitch 518 engages the contact member 518, the table 8| is turnedthrough a half-revolution. The guide members 58 are relowered to theirnormal position when the master switches 518 and 518 engage the contactmember 512. And the cam |05 is restored to its original, lowered,position, to permit the table i 2 to become relowered from its effectiveto its ineffective position,

when the master switches 518 and 519 engage the contact member 518,whereupon the feeding I by the breaking of its circuit throughseparation of the contact members 356 and 358', and the machine is readyfor another cycle of operations.

The electric-circuit connections for effecting these operations areillustrated in Fig. 82. The contact member 568 is connected by aconductor 51| to the coil 3i8 for effecting the actuation of the shaft48 through a half-revolution to effect the raising ofthe guide members55. 'I'he contact member 512 is connected, by conductors 513 and 12, tothe coil 3|6 for effecting the actuation of the same shaft 48 throughanother half-revolution to effect the lowering of the guide members 55.The contact member 510 is similarly connected, by a conductor 515, tothe coil 332 for actuating the shaft 84 to turn the table 9i throughhalf-revolutions. The contact member 514 is connected, by a conductor516, to the electromagnetic coil 318 for lowering of the table I2`
